A year ago IBM was joining OpenJDK

In the past 12 months Java SE 7 was filed as a JSR and delivered with implementations from both Oracle and IBM, the JCP started working again with substantial progress made for Java SE 8 (now scheduled for the summer of 2013) and Java EE 7.

Apple, Azul, SAP and Twitter have also since joined the OpenJDK project.

The list of blogs collected last year on TheAquarium make for an interesting read given all that has happened since. Java is Moving Forward.
